On August 14, 1995, at 1936, eastern daylight time, a Beech 23, N4798J, sustained substantial damage during a forced landing near Spafford, New York. The commercial pilot and two passengers were not injured. Visual meteorological conditions prevailed, and no flight plan was filed. The local, personal flight departed the Skaneateles Aero Drome, Skaneateles, New York. It was conducted under 14 CFR Part 91. In the NTSB form 6120.1/2, the pilot stated: ...Proceeded south to approximately 2500 feet and approximately 10 minutes after departure...the engine developed a loss of power. Mixture, throttle, boost pump were checked. I then turned east toward open fields. The airplane continued to lose power and altitude....I then set up for best glide speed and landed the airplane in an open field impacting brush and trees at the edge of the field.... Postaccident examination by the Federal Aviation Administration (FAA) Inspector did not reveal any preimpact anomalies with the airframe or engine. Additionally, the FAA Inspector stated that vapor lock was suspect; however, could not be confirmed.
